Caerphilly CF83: electric underfloor heating not working
Straightforward electric underfloor heating not working for Caerphilly property, including the paperwork that goes with it. Caerphilly and the CF83 postcodes are handled by the same electrician throughout.
Do this before we arrive
- Check the board for a tripped device on the heating circuit before assuming the mat has failed. Ask if you want it explained on site.
- Note when it last worked and whether any flooring, plumbing or joinery work happened around then. That is measured, not assumed.
- Where the survey supports it: confirm the thermostat is actually calling for heat — set point well above room temperature, and check any holiday or timer mode.
One thing worth repeating: underfloor heating circuits require RCD protection, and a mat that fails insulation resistance testing must not be energised again until it has been repaired or isolated permanently.
If the property has been altered, extended or let out, electric underfloor heating not working deserves more than a quick look.
We work to the current edition of BS 7671 and note where an older installation departs from it and why that matters. The schedule of results records it either way.
electric underfloor heating not working tends to be judged on the finish, but the part that matters sits behind the wall and only shows up in the readings. On new-build estates around Bedwas and Trecenydd it is worth ten minutes of anyone's time.
We would rather turn a Caerphilly job down than take on something we cannot certificate honestly. Around CF83 it is the single most common reason a job runs long.
Questions asked during the visit get answered during the visit; there is no benefit to either of us in keeping it mysterious. For new-build estates around Bedwas and Trecenydd that detail matters more than it does elsewhere.
Where an installation has been extended over decades, the sensible approach is to establish a baseline before adding anything else to it. We would explain the same thing on site, just with the board open.
The cost drivers here are access and condition rather than parts. A failed floor sensor reading open or short circuit is the one that moves a quote most. That is the honest version, rather than the version that sells more work.
Questions before booking are free, and often end the conversation there. If you have had a quote elsewhere, we are happy to look at it and explain the differences.
Everything below applies to electric underfloor heating not working in Caerphilly and its immediate neighbours.
What tends to be behind it
- You may already have spotted a tripped RCD or RCBO on the heating circuit yourself.
- Physical damage to the mat, typically from a fixing. If it is not this, testing narrows it down quickly.
- A failed floor sensor reading open or short circuit is the reason a phone quote would be a guess.
- On this type of work, a thermostat at end of life, or one whose sets the sequence of everything after it.
What gets done
- On site in Caerphilly we measure the mat's resistance and insulation resistance against.
- We that sequence tells us in minutes whether you are so the record matches what is actually installed.
- For new-build estates around Bedwas and Trecenydd in particular we measure the mat's resistance and insulation resistance against.
For Caerphilly work: mat, sensor and thermostat testing quoted as a single diagnostic visit; parts and repair priced after readings.
